With the development of network technology, the future network is an open and reconfigurable network architecture whose functions are reorganizational, capabilities are programmable and managements are reconfigurable. According to the feature of the future network that is application-oriented reconfigurable, this paper proposed a design of integrated network management system. The system is based...
The high energy consumption in the local network often leads to energy hole problem in wireless sensor networks (WSNs), It easy to make the WSNs dying prematurely. The effective way is the evenness of energy consumption of each node. Unlike other existed schemes, we sliced the circular field into concentric circular bands of fixed width. By combining the direct transmission protocol and hop-by-hop...
In this paper, we present a new semi-automatic chemiluminescence immunoassay analyzer, which is based on photons counter consists by the photomultiplier tube. The photons count efficiency is very high, which makes the test result be more sensitive and steady. A calibration circuit was presented in this paper, which was used to check the veracity of the photons counting. Significantly, this paper presents...
In order to build extended logic manufacturing cell (ELMC) supporting rapid extended manufacturing (REM), the technology for ELMC based on similarity theory and clustering analysis was proposed. The question of ELMC was expounded, and computation of process similarity factor was introduced. The construction algorithm of ELMC was detailed discussed. Firstly, similarity matrix of processing task was...
Petri Net is an important tool for concurrent system modeling and analysis. It is a combination model that can be represented by graph; it can express relations of concurrency, sequence, synchronization in system by a visual way. This paper analyzed PPPoE protocol using Colored Petri net. Firstly, the definition of Colored Petri net and PPPoE was introduced, secondly, the working principle of PPPoE...
Cancer is one of the most critical medical emergencies, and prevention of tumor cell multiplication has always been a great challenge. Present day technology to cure cancer such as chemotherapy using Gamma Rays and Laser Endoscopy have several risks involved in them. These techniques have high probability of destroying the healthy tissue cells while treating the tumor cells. Nanotechnology, the promising...
This paper proposes a new method for shape signature which is based on Homotopic deformation(HDBS). HDBS use the minimum circumcircle which encircle the shape as the deform template, and use the path length derived from deformation as the sampling data. This method ensures the disjoint among the paths of deformation, avoids crossing by paths and contours except at origin, every point in contour can...
Sys-log message is the importance data which could present information about internet source-destination connection of all IP address nodes in each network server. These sys-log messages must be securely kept in database in case of being referenced, such as legal requesting. The objective of this research was to develop a security protocol of system log message database manipulation. Message was split...
The electronic counter could measure the frequency, period and phase difference by combining the intelligent virtual instrument technology. And expanded the measurement by using of the interpolation technology. It included hardware and software. Hardware included the MCU, PLD, signal shaping circuit. Software included man-machine interface, communications, data processing module. The frequency was...
Recently, distributed video coding (DVC) has attracted much more attention with advances in low-complexity encoder and flexible architecture, which could be effectively applied in mobile video communication and video surveillance network. But the gap with the conventional video codecs is still large. One of the key factors is the quality of side information as it directly affects the system's rate...
The energy constraint of sensor nodes is the key factor that restrict the life of wireless sensor networks. So an effective method of dynamic power management (DPM) that based on grey model is proposed to make economical use of energy. Historical data collected of sensor node is used to predict the future value in this method, while the parameters are adjusted automatically in the process of prediction...
A concept of role analysis is presented. The role analysis extends the traditional use case analysis in the area of actor properties investigation. The role analysis algorithm forms required images of actors based on given use cases and technical constraints. The algorithm can be used to determine required skills of system users and to form images of external systems that interact with the designed...
